Master → Converter
The master transfers the data in the "Combined Transaction Type 2" (CTT2) to the converter
and writes it to r2050[1] and r2050[2].
To process these values in the converter, you must appropriately interconnect r2050[1] and
r2050[2] in the converter. This means, when the control sends the speed setpoint, you must
interconnect parameter p1070 (source for the main setpoint) with r2050 as follows:
p1070[0]=2050[1]
Note
Internal interconnection with Macro 34
If, when commissioning, you select Macro 34, then the main setpoint is internally
interconnected with r2050[1].
Once a setpoint has been transferred completely, the setpoint present in the control will
be transferred as next setpoint. Any setpoint changes made during the transfer are not
considered.
7.7.4.2 Acyclic communication - standard
This type of acyclical communication supports the ID read request and the diagnostic read
request. All other requests receive the "request not implemented" message response.
• ID request:
– Master → slave
– Slave → master
0DQXIDFWXUHUV,'
3URGXFW,'KH[ KH[%%KH[
• Diagnostic request:
– Master → slave
– Slave → master no error
Slave → master general error
The following response is issued for all other write or read requests:
• Read requests
• Write requests
7.7.4.3 Acyclic communication - manufacturer-specic
The manufacturer-specic acyclical communication is performed via data record 47 in PIV
format. The PIV (parameter channel) format structure is identical with that for the USS
parameter channel.
